Note 1: External power devices may require heat sinking. Note 2: Commercial grade parts are designed to operate over the temperature range of – 40 °C to 85°C but are neither tested nor guaranteed beyond 0 °C to 70°C. Industrial grade parts specified and tested over –40 °C and 85°C are available on special request, consult factory. Note 3: TJ calculated from the ambient temperature TA and the power dissipation PD according to the following formulas: LT1166CN8: TJ = TA + (PD • 100°C/W) LT1166CS8: TJ = TA + (PD • 150°C/W) Note 4: ITOP = IBOTTOM Note 5: The input resistance is typically 15M Ω when the loop is closed. When the loop is open (current limit) the input resistance drops to 200 Ω referred to Pin 3. Note 6: Maximum TJ can be exceeded with 50mA operating current and simultaneous 10V and – 10V (20V total). Note 7: Apply ±200mV to Pin 2 and measure current change in Pin 1 and 4. Pin 3 is grounded. Note 8: Note 9: For Linear Operation, Pin 1 must not be less than 2V or more than 10V from Pin 3. Similarly, Pin 4 must not be less than 2V or more than 10V from Pin 3. Pin 1 = 2V, Pin 4 = – 2V, Operating current 15mA and RIN = 20k, unless otherwise specified. 1 2 3 4 8 7 6 5 TOP VIEW VTOP VIN VOUT VBOTTOM SENSE+ ILIM + ILIM – SENSE– N8 PACKAGE 8-LEAD PDIP S8 PACKAGE 8-LEAD PLASTIC SO +1 PSRRCC = gmCC2 – gmCC10 gm CC2 PSRREE = gmEE2 – gmEE10 gm EE2 LT1166CN8 LT1166CS8 |
